1) PersonA sent mail through ServerA to PersonB at ServerB
2) ServerA Accepted the mail from PersonA then attempted to connect to ServerB to give it the mail
3) upon connection from ServerA to ServerB, ServerB refused the connection (most likely a NAT or Route problem).
4) ServerA then replies to PersonA and says &quot;I attempted to send the mail, it was refused, but I'll try again in an hour&quot;.

The way to test to see if this is a problem w/ ServerB is to pop up Run and put in &quot;Telnet Server_B_Address 25&quot; and see if it connects. If it does not then there is a problem w/ ServerB. I hope this helps. ~Jeffrey A. Ellman
